drop pitman arm

[SW86]

at what point do you really need one?

[JeepcoMJ]

there are two reason's you would need one. both involve keeping the drag link parallel to the track bar. both are associated with lifts 5" or bigger, and are not really necessary until you reach 6.5"

 

A.) drop upper track bar bracket down.

 

2.) Over The Knuckle steering

[mnkyboy]

The track bar causes the axle to move side to side as the suspension travels,if your steer link doesn't match the movement of the track bar your steering wheel will jerk side to side(bump steer) as your suspension moves.

 

The two links must be parallel so they will move the same,this is where various length pitman arms come into play. They allow you to move the steer link up or down to match the track bar.
